Azteca Airlines last week took delivery of its first Boeing Next-Generation 737-700 jetliner, making it the first carrier in Mexico to operate the advanced-technology airplane. Azteca will operate the airplane through a leasing agreement with Pegasus Aviation, Inc. Azteca is a new regional passenger airline that began operations earlier this month with 737-300s. Boeing will deliver a second 737-700 to Azteca later this year. The 737's proven performance record, spacious new interiors, low operating costs and operational flexibility have made it a popular choice for successful airlines throughout Latin America.
